Pathophysiology of pulmonary embolism
Fisiopatología de la embolia pulmonar
Resumen:
The obstruc"tion of the arteropulmonary blood flow is the physiopathological element which is common to all pulmonary embolism. In many cases, apart from mechanicalblockage, there is arteriolar vaso constriction which contributes to the increase , of vascular pulmonary resistence. Thus pulmonary hypertension due to vascular causes may appear, though its interpretation varies according to the intensity and severity of onset . Pathogenesis of pulmonary infarction and respiratory alteration following pulmonaryembolism, are also analysed.
La obstrucción del flujo sanguíneo arterial pulmonar es el elemento fisiopatológico común a todo embolismo pulmonar. Además del bloqueo mecánico existe en muchos casos vasoconstricción arteriolar que contribuye al aumento de las resistencias vasculares pulmonares. Puede así generarse una hipertensión pulmonar de causa vascular que tendrá distinta traducción según la intensidad y agudeza de instalación. Se analiza además la patogenia del infarto pulmonar y las alteraciones ventilorrespiratorias que siguen a un embolismopulmonar.
